**To keep the pit area safe, each rider is allowed a pit pass for themselves and 4 more for their pit. Each person must purchase a pit pass and sign the waiver, NO EXCEPTIONS.
Pit passes must be signed for by the person wearing it. (For example, a parent cannot buy 4 pit passes to hand out later.) Insurance regulations do not permit this.
People in the pit area must park their vehicles in the general parking lot. Only the truck/trailer that the rider is pitting out of allowed in the pits.
YOU MUST BE PRESENT WITH YOUR RIDER to get a pit pass. NO EXCEPTIONS. Once you have purchased a pit pass and signed the waiver, you can come and go as you please.
You cannot show up to purchase a pit pass without your rider present.
DO NOT buy a ticket either online or at a ticket outlet if you are planning on being in the pits. That ticket will not get you into the pits and is nonrefundable.
A pit pass will get you into the bleacher area to watch, but you cannot consume alcohol with a pit pass on. If this is observed, your pit pass will be cut off.

Gates open at 4:30 pm and the racing starts at 6pm.
No outside food or drink is allowed. Please support our vendors!
Please be courteous to security as they check your bags. They are only doing their job.
No pets please.
Blankets, lawn chairs and EZ-UP type shelters are allowed on the Terrace side. The EZ-UP
Must be kept in the lowest position and not block anyone above/behind you. If it blocks any view
You may be asked to take it down.
